Thank you for replying on my posts. I was trying to find out how to change the strength of hydrogen bonds in water for my lab report, and since you mentioned surface tensions of aqueous solutions, I researched which solutions could change surface tension. Based from a quick search, there were alot of solutes that could be added to water to change its surface tension, but doesn't necessarily cause hydrogen bond formation on the new mixture. How do I execute my research further?

Further? You can look at hydrogen bonding in other liquids (alcohols, organic acids, whatever). Three (?) center bonding in boranes. Lewis acids and bases (not necessarily hydrogen bonding, but another very similar effect).

it seems like acidic solutions strengthen hydrogen bonds while basic solutions weaken hydrogen bonds. for example, ammonia, a basic solution, has a very weak hydrogen bond while hydrogen fluoride, an acid, has a very strong bond. is this what you mean about lewis acids and bases?
